2.3.14 Carrier Frequency and Power Measurements Using Pulsed RF Signals
This section describes how to measure carrier frequency, peak power and average power of pulse modu-
lation signals which are used in the pulse radar and so on.
Measurement conditions: The signal to be measured has a frequency of 1.1 GHz, a pulse repetition rate
of 0.333 kHz, a pulse width of 0.8
µ
sec and a peak power of 3 kW.
The external attenuator with an attenuation of 50 dB is used on this measure-
ment.
Use appropriate parameter values when taking measurements in the example
shown below.
CAUTION:
The maximum amount of power that can be input to the analyzer is +30 dBm (1 W). When mea-
suring a signal power whose value exceeds this limit, connect an external attenuator so the power
cannot 30 dBm.
Setup
1.
Connect the unit under test as shown in Figure 2-141.
Figure 2-141 Setup for Measuring Pulsed RF Signal
Power on
2.
Turn the analyzer and the unit under test power on.
Setting the unit under test
3.
Activate the signal output for the unit under test.
Initialization
This resets the current settings to the factory defaults or user-defined presets.
4.
Press SHIFT and CONFIG(PRESET).
This sets the analyzer to its presets values.
Setting the measurement conditions
This changes the analyzer settings so that the input signal is displayed more clearly.
